  • Water-soluble or water-disintegrable copolymer
    Patent number: 10308743
    Abstract: A copolymer is based on ?-?-unsaturated monocarboxylic acid, wherein the copolymer has a molar mass <100 000 g/mol. A process of preparing the copolymer compound includes mixing a copolymer in a melt with an impact modifier under action of shearing forces, a proportion of copolymer and impact modifier being selected preferably such that the copolymer forms a continuous phase and the impact modifier forms a discontinuous phase.
    Type: Grant
    Filed: October 2, 2017
    Date of Patent: June 4, 2019
    Assignee: BellandTechnology AG

  • Pack containing a dry alkaline solid
    Patent number: 5863885
    Abstract: A pack contains a dry alkaline solid (1), which produces in an aqueous media a pH value exceeding 10, which consists of at least a one-layer packaging and which contains at least one polymer film (3) soluble in aqueous alkaline media. The polymer film contains two phases, whereby the continuous phase is made of a copolymer or terpolymer of .alpha.-.beta. unsaturated monocarboxylic acid which has a COOH group and the discontinuous phase is formed by a polymer which has an epoxy group, whereby both polymers are bonded in the boundary layer through esterification between COOH groups of the copolymer or terpolymer and epoxy groups of the discontinuous phase polymer.
